Xây dựng đường cong cường độ–thời đoạn–tần suất mưa hướng đến thiết lập bản đồ ngập lụt cho khu vực bán đảo Cà Mau

Abstract

In recent years, heavy rainfall events have appeared frequently in the Ca Mau peninsula area, causing local flooding and affecting many aspects of life in the area. According to a report of the Ministry of Natural Resources and Environment, rainfall is an increase tend in intensity and frequency in the Ca Mau Peninsula as a part of climate variability. Heavy rainfall tends increase, which will cause the local flooding events in which has low terrain and less severe drainage systems. It is, thus, necessary to proactively prevent adverse effects from flooding events on people's lives. Therefore, the goal of the study is a) to simulate rainfall intensity-duration-frequency (IDF) curve of the extreme rainfall events using the CumFreq software for the Ca Mau Peninsula and b) toward to establish inundation maps based on the simulated data from rainfall IDF curve, contributing to proactively minimize the potential risks of flooding as well as proactively adapt the impacts of climate variability.
